Package Exports

binary-search

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (binary-search) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

binary-search

This is a really tiny, stupid, simple binary search library for Node.JS. We wrote it because existing solution were bloated and incorrect.

This version is a straight port of the Java version mentioned by Joshua Bloch in his article, Nearly All Binary Searches and Merge Sorts are Broken.

Thanks to Conrad Irwin for, ironically, pointing out a bug.

Example

var bs = require("binary-search");
bs([1, 2, 3, 4], 3, function(a, b) { return a - b; }); // => 2
bs([1, 2, 4, 5], 3, function(a, b) { return a - b; }); // => -3

Be advised that passing in a comparator function is required. Since you're probably using one for your sort function anyway, this isn't a big deal.
